A MILESTONE IN THE ART OF SOUND REPRODUCTION

The 4-channel system affords the world of music a number of interesting
possibilities that the conventional 2-channel system cannot begin to
offer.

Sansuis OS 4-channel system has been developed to fully exploit these
possibilities, and its technical and artistic excellence is widely acclaimed.
Since its original conception, it has undergone a significant enhancement
in the form of the revolutionary OS Vario-Matrix, which enables it to
provide inter-channel separation in excess of 20dB.

It has already been subjected to the severe professional scrutiny of
hundreds of recording and broadcast engineers around the world, and
found to pass the tests of musicality, compatibility and economy.

A multitude of major record companies in the U.S.A.. Europe and Japan
have released disc records and cassette tapes recorded by the 08 system.

All commercial FM stations in Japan are now offering OS 4'channel
programs, and so are WFMT in Chicago and other leading statiOns in
the U.S.A.

The RIAA (Record Industry Association of America) have approved
the OS encoding system as its standard.

The professional OS 4-channel Encoder introduced here fully benefit
from these accomplishments and experiences. Not only are their perform-
ances certain to satisfy you, but their versatility, durability and appear-
ances are on a par with the world's highest standards of professional
hardware.

Test the instruments for yourself soon, and witness this striking break-
through in the art of sound reproduction.

4'CHANNEL ON THE AIR(A QUICK GUIDE TO OS FOR FM 4-CHANNEL BROADCASTING)

WHAT CAN YOU EXPECT FROM 4-CHANNEL FM?

1. Fully dimensional music broadcasting - more realistic and totally
new. Especially important if you are a music-oriented station.

2. New audience -- more listeners tuning in for 4-channel sounds.

3. More revenue ~ promotional dollars and co-op funds from 4-channel
equipment manufacturers, distributors and dealers are available now l
Record manufacturers and dealers are also extremely interested in
getting more air time for 4-channel sounds.

4. A fresh new image for your station - "The all-quad spot on the
dial

CAN YOU BROADCAST IN 4~CHANNEL TODAY?

1. Matrix encoded 4-channel materials -- records, tapes made with the
Sansui OS or Columbia SO systems - can be broadcast through your
regular 2-channel transmission system. Absolutely nothing else is
required. Not some hazy time in the future, but NOW, today.

2. OS Encoder enables you to air:

demodulated CD-4 or Ouadradiscs,

'any other discrete 4-channel material such as 0-8 cartridges and
Surround Stereo" discrete 4-channel music tapes,

4-channel live" concerts direct from the concert halls or festival
stages.

'decoded SQ materials, and

'4-channel commercials or jingles, of cource.

Your audience will receive such 4-channel material as regular stereo (or
mono) with rather enhances quality on his stereo equipment. There is
absolutely no loss of 4-channel information. If a listener owns one of
the matrix 4-channel decoders (and theres lots of them around), he
hears them in 4-channel at home.

WAITING FOR DISCRETE?

You'll probably wait a long, long time.

Matrix decoders are already widely accepted and in the hands of millions
of consumers. You now have a matrix 4-channel audience.

With the recent sophisticated matirx decoders such as OS vario-matrix,
you are getting over 20:18 separation across all four channels. With the
discrete system. you will give you the same but no more.

For discrete 4-channel broadcasting, these factors must be considered:
SCA services must be ceased in all areas.

The dozen of the proposed discrete broadcast systems must be stand-

ardized to one, and that one must wait for approval from the FCC
and other official bodies.

The FCC and others must then change their regulations accordingly.

'Demodulators made specially for this purpose must then be mass
produced and introduced to the market.

'Consumers who presumably own matrix and CD-4 demodulators already
must purchase yet this additional unit.

You have 4-channel now with the matrix. There's no sense waiting for
discrete.
